Back of chamber oversize?http://benchrest.com/showthread.php?99295-Back-of-chamber-oversize&goto=newpost

The manufacturer says you can use this gauge for other calibers by using the appropriate case length gauge. I tried to do this for my 30BR brass and found that the fired brass would not go all the way into the gauge. My fired 6ppc brass goes into its gauge fine. This suggests to me that the chamber in the 30 BR barrel is oversize near the rear. Does that sound correct?

I have a customer who is inquiring about having muzzle brakes installed on a few rifles and asked for recommendations on which brake to buy. I told him I don't know much about them, but I do know some folks that do.

So...what say you? Got any recommendations?

Also, a couple of these rifles are sporters in 7mm ŗnd I have some concerns about turning down the muzzles for threading and what is a safe minimum diameter. Any guidance you could provide on this subject would be greatly appreciated.
